Effect Stack offers a variety of image filters that can be stacked together and saved as presets that you can reuse. The filters' effects ripple downward through the stack, changing the current state of the selected image(s). All changes are reversible and visible immediately. It is possible to work on multiple images at once and the application supports many image formats, including RAW images.
